All 10 Canadians thought to be at risk from the hantavirus are back on Canadian soil and are currently in isolation, health authorities say.

The outbreak started last month aboard a luxury Dutch vessel during a weeks-long cruise that kicked off April 1 in Argentina. Three passengers from the MV Hondius—a Dutch couple and a German woman—have since died and several others have developed symptoms of the rare rodent-borne disease.
